ROTARY POWER DEVICE.

Application filed March 10, 1,919. Serial No. 281,892.

To all 'whom t may concern:

Be it known that I, ELLICK H. GoLLiNes, a citizen ofthe United States,and a resident of the city of Chicago, county 0f Cook, and State ofIllinois, have invented certain new and useful Improvements in RotaryPower Devices; and I do hereby declare that the following is a full,clear, and eXact description of the saine, reference being had to theaccompanying drawings, `and to the numerals of reference markedthereon,which form a part of this specification.

My invention has reference more particu larly to a rotary power devicecomprising eccentrically arranged members having iiuid compartmentstherebetween, whereby fiuid is passed throughthe device by rotation ofeither member. y Y

It is an object of my invention to provide an improved rotary powerdevice which may be used either as a pump or motor.

Another object of my invention is to providel a rotary power devicecomprising eccentrically arranged inner and outer members with achambertherebetween having swinging partitions, operating upon rotation ofeither member to afford correspond- K ing enlarging and diminishingcompartments adaptedto effect a transfer of fluid through the device.

Anotherobject of my invention is to pro` vide a rotary power devicevcomprising eccentrically arranged inner and outer mem bers with achamber therebetweenhaving swinging partitions, operating upon rotationY of one of the members to afford corresponding enlarging anddiminishingI compart-4 ments to effect a transfer offiuid through f thedevice, the said partitions being adapted to interlock with one anotheras the de' vice is operated, to afford an effective sepa- 'rationbetween theenlarging and diminishing compartments. Y

A furtherobiect of my invention is to provide a rotary power devicecomprising eccentrically arranged rotary members either of which may beheld stationary as the other is rotated to thereby effect a transfer oflfluid through the device, and in which each member rotates only in onedirection which is opposite to the direction of rotation of the othermember, and such rotation of either member effects a transfer of liuidin the same manner through the device. In other words, the device may bedriven in Specification of Letters Patent.

As shown on the drawings: Referring first to Figs. 1 to 9 inclusive, thereference numeral l indicates the base of the device upon which aremounted pairs The bearinfr support 3 is cut away at 6 for a purpose 2hereinafter indicated and thus differs from its corresponding bearingsupport 2, but otherwise the kbearing supports of each pair are alikeand serve the' same purpose. Each of these bearing supports takenthrough the axis- Y of bearing supports 2 3, L.1 -4c, and 5 5. i

is kcomposed of a pairV of half sections, as

shown in Figs. 8 and 9, with opposite semicircular half bearings, attheir upper; ends, which are clamped around the portion of the deviceengaged therein, by means of bolts 2l and 22, which connect the halfsections above and below the bearings.

Mounted between the bearings 2 and 3, is a casing comprising a drum 7which is closed at its ends by the plates 8 and 9,v each of which isprovided with an axial sleeve or hub extension 49, journaled in therespective bearings 2 and 3 to support the casing for rotation.

Mounted within the casing 7-89 is a hollow cylinder 10, the end walls 11of which are spaced apart so as to lit closely against the end plates 8and 9 of the casing and permit relative rotation thereof, and a tubularhub 12 is arranged eccentrically on each end wall 11 of the cylinder 10,and in alinement with one another, each of said hubs being journaled inthe sleeve 49 of its adjacent end plate 8 or 9, as shown in Fig. 7

Secured within each hub 12 or, if desired, made integral therewith, is ahollow shaft or pipe 13, which extends outwardly and is journaled in thebearing 4 and extends into the bearing 5. Each bearing 5 has mountedtherein the enlarged end 14 of a pipe which communicates with the hollowshaft 13, and has the end of the latter journaled therein as shown inFig. 7, one of these pipes, which serves as the inlet when the device isused as a pump and as the outlet when used as a motor being indicated at15, and the other, which serves as the outlet when the device is used asa pump and as the inlet when used as a motor, being indicated at-16.Each of the enlarged ends 14 is held aga-inst rotation in its respectivebearing 5 by set screws 17a, which are threaded through the bearing andengage in the wall of the enlarged end 14.

The inner end of each enlarged pipe end 14, and the outer end of eachhub 49, are similarly formed to provide a fluid tight joint with therespective pipes 13, and per- Y mit relative rotation, and to thisendeach has a stuning box with packing material 17 therein which is pressedinto the stuffing box by a packing ring 18, the latter being clampedagainst the packing by bolts 19, secured to the end of the enlarged pipeend 14 or hub 49, and engaged through an annular flange 2O of thepacking ring The cylinder 10 is divided, intermediate of its ends, intoseparate compartments 23 and 24, by means of a diametrical partition 25,which is offset at the center as shown in Fig. 3, so that thediametrically opposite arcuate slots or openings 26 and 27 communicaterespectively with the compartments 23 and 24, the ends of these slotsbeing separated by the intervening wall portions 28 and 29.

A, plurality of partitions 30 are pivotally mounted in the casing 78-9,at equal intervals,` and adjacent the inner periphery of the drum 7, onshafts or bolts 31, which extend between and through the end walls drum7 and cylinder 10 8 and 9, so as to support the partitions and alsosecure the end plates to the drum, and these partitions are engaged bysprings 32, so that the inner ends of the partitions bear constantlyagainst the outer periphery of the cylinder 10. suitable width to engageclosely against the end walls 8 and 9, of the casing without interferingwith their pivoted movement, and the pivoted end of each partition is ofcylindrical contour to fit and rock in correspondingly shaped transversegrooves 33, so that these partitions serve as valves to separate theannular space between the cylinder 10 and casing 7-8--9 into separatecompartments and prevents appreciable leakage therebetween.

Obviously, as the cylinder lOand casing 78-9 are eccentrically arranged,rotation of either one, while the other is held stationary, results in asuccessive swinging of the partitions 30, those occupying the spacewhere the walls of the cylinder 10 and drum 7 are closest together beingswung outwardly as shown at the bottom of Fig. 2, and those occupyingthe space where the cylinder and drum are separated the' greatestdistance being swung inwardly by their springs 32, as shown at the topof Fig. 2, and inasmuch as the inner ends of the partitions bearconstantly against the cylinder 10, those intermediate of these twopositions are at successively increasing or decreasing angularity to theinner face of the drum 7.

Of course, as the cylinder 10 or casing 7-8-9 revolve,lthe partitions 30are constantly changing their positions, and the wall portions 2S and 29between the slots 26 and 27 are sufficiently long so that one, at least,of the partitions 30, is engaged therewith at all times, thuseffectively separating one halt of the annular saace between the whichhalf communicates through the slot 26 with the chamber 23) from theother half of the space between the drum and cylinder (which halfcommunicates through the slot 27 with the chamber 24). n

Each of the partitions 30, at its free end, is oset so as to have a shoeportion 34 with two angular faces 35 and 36, the former of which fitsand engages the periphery of the cylinder 10 as it rides along the slotseparating portion 29 of the cylinder wall and insures suliicientengaging surface to prevent leakage between the chambers at oppositesides of the partition, and the latter of which fits and engages, forthe same purpose, the periphery of the cylinder 10, as it rides alongthe slot separating portion 28 of the cylinder wall, these being the twopla-ces of Contact of the partitions 30 with. the cylinder wall whereleakage is to be obviated to as great an extent as possible.

As a further measure to avoid leakage as These partitions are of thepartitions ridealong the portion 28 of the cylinder wall, each partitionis provided withan angular or rib-portion 37, on the outer face, which,as the end of the partition slides over lthe cylinder portion28, engagesand 'is held against the cylindrical surface of the outer end ofthepreceding-partition, as shown in Fig'. 2.v Such engagement, however, byreason of the Acylindrical surface with which the rib v37 contacts, doesnot interfere withthe l`movement Vof the par-l tition, engaged by therib 37, which is required to maintain its'frce .end engaged with thesurface of the cylinder-10. In order to lapply power to this device 'forroperating-it as a pump or to transmit power therefrom, 'if usedas v`amotor, the side wall 9 of the casing 7-8-,7-9 has an annular flange 38,at the `outer iside, 4or a circular series of lugs, if preferred, towhich a gear ring 39 is secured, the bearing support 3 being cut awayat-6 to accommodate this gear,and a gear wheelf40 is also" keyed `atf41on the tubular shaft 13, so thateach rotary-element of the device mayreceive or transmit power. 'When one of .the rotary elements is rotated,the Zother is usually maintained stationary, and for the purpose anumber of set screws 42 are threaded through the bearings 4, andadapted, when the shaft 13andlcy1- inder 10 are to be held stationary,to 'be turned down into engagement with -countersinks 43 (see F ig. 9)"provided `therefor kin the shaft 13. These cap screws vare Withdrawn orremoved,-when`the shaft 13 and cylinder l0 are to rotate. l

`Similar cap Vscrews 44 are threaded-into the bearings 2 and 3,so as toengage similarcountersinks in the hubs 9 ofthe end plates Sand 9 of thecasing of the device when the latter isto be held stationary.

In Figs. 10 and 11, I have shown a modiication of my invention which isthe same as the previously described structure, except as to thepartitions `45, and the same .reference numerals are used to designatethe parts that are alike inbothl structures.

The partitions45, in this modified :structure have a long inner face-46,to ride on tlie t e slot separating portion 28 of the'cyhnder wall, andthis face 46 is yformed on a radius of curvature equal to the 'distanceof the aXis of the hubs 12 from the most eccentric point on the outerface of the cylinder '10, so that as such point comes into contact withthe face 46, there is no further pivotal movement of the partition untilthis point moves out `rof contact with theface 46. The-back of thepartition .also has a rib or angular flange 47, whichcoperates with .thecylindrical pivoted end of the preceding partition in the samemanner asthe rib 37 of the I previous construction and as the partition,

whileriding over the slot separating portion Yvpreceding partitionyprevious to the disengagement of Athe rib of such precedingpartitionwith its preceding partition, thus insur- 'i ing `a thoroughseparation between the intakeand outlet compartments of the device.`

This separation is also assured by the increased extent of engagement ofthe surface with thewall ofthe cylinder `10 as `it ridesoverftherslot,separating portion'28 thereof` Theoperation is as follows:W'Assumingthat the device is to be used as apump, this ymay beaccomplished by rotating Qeither the drum 7---8-49` or the cylinder 10intheproper direction `while the other remains-stationary, or` byrotating -both in opposite directions. Gearing may bejconnected-Swi'ththe gears l39and 40 to rotate either and` a'dapted,when one is rotatedto hold jthe otherfrom rotation However, for the purpose ofillustration, and to provide a simplesand reffective means ofcontrolling the independent rotation of each,I have shown the 'setiscrews 42 and 44, the former of which fareadapted tolockthe cylinder l0from rotation and the latter of which similarly lock the casing 7 -8-9.

lIf it is .desired to pump by rotating the i casing 7-8'f9,-the setscrews 44 are -withdrawn sufliciently to permitirotation thereof,

and the set screws 42 are turned down so as `to seat in thecountersinks43 onfthe shaft or tube 13, and `thereby hold the cylinder10 attached thereto in a stationary position.

Powerk is thenapplied to the gear ring `39, torotate the casing 7-8-9inthe direction indicated by the arrow A in Fig. 2, and the pipe `15isconnected with the source of fluid supply land thepipel connectedtoconvey thefdischarge from the'pump to the point desired. r

The rotation of the 'casing 7-*8-9 ,car-

the ends thereof being maintained in contact withfthe surface of thecylinder by the ten-4 sion` of thesprings and also,'at the points ofgreatest andv` least distance betweenl thecylinder 10 anddrum 7,whichfis the top and partments, certain ones of which communicate withoneanother through theslots 26" and 27 and. their respective chambers 23and 24, and itwill be 'observed that by reason of the intervening wallportions 28 and 29,

apartitionis'at all times engaged with the wall fof the cylinder 10 atthe point 4of great-- ries the partitions 30 around the cylinder` l0, Y

est separation betweenfthe drum 7 and cylinder and another partitionatlthe point of least separation of the drum fromthe cylinder so as toprevent communication between the compartments, between the partitions30, which are in communication with the slot 26 and chamber 23, and thecompartments in communicationwith the slot 27 and chamber 24. Thechambers in communication with the slot 26 are graduallyenlarged as thedrumv7-,-8-9` rotates inthe directionindicated by the arrow` A and fluidis drawn in through the pipeY 15, hollow shaft 13, cylinder chamber 23and slot 26 toiill these constantly enlarging compartments, and providewhat is hereinafter termed the suction side of the pump, andas eachcompartment reaches its greatest capacity, the preceding partition isriding over the wall portion 29 of the cylinder l() .and

the following partition moves over the Vwall portion 29 so as tointerrupt communication with the slot'26 and isolate this compartmentfromv the following compartments at the suction side of the pump.'lv

i The compartments between'the partitions 30 which are in communicationwith the slot 27 ,are constantly decreasing inl capacity as the casing7-8-9 rotates in thedirection A and afford what is hereinafter termedthe pressure or discharge side of thepump, `and as each compartment,which :passes overthe cylinder wall portion 29 andi'has been Visolated.from the suction sidevof the pump,

comes into communication with `the slot 27 it is gradually decreased insize `so thatthe fluid therein is forced out through the slot.

27 cylinder chamber 24,- Ahollow. shaft l13 and pipe 16. The continuing.rotationl of the drum 7-,8-9, and the resilient continuous enlargementof compartments at the:

suction side of the pump and transfer'of fluid therefrom to thedischarge side of the.y pump, and the continuous diminution .in .size ofthe compartments at the discharge jside.. of thepump. effects acontinuous passage of fluid through the pump. 1

Then the pumping isto beV affected byl rotating the cylinder, the setscrews filare turned down to hold the casing 7-8-9 stationary and theset screws 42 are withdrawn sufiiciently to permit rotation of .thecylinder 10. Power is then applied to the Agear results in a' continuousdiminution of theA compartments between the `partitions 30, in`

communication withlthe slot 27, and cylinder chamber 24,' and a constantyenlargement of the compartments inI communication with v the slot 26and chamber 23, and-a constantvsuction of fluid in through thepipe 15,hollow shaft 13, cylinder chamber 23 and slot 26, and `transfer ofyfluidfrom the suction side to the discharge side of the pump, and exhaust ofthe fluid through theA slot 27, cylinder chamber 24, pipe 13 andpipe 16,as in the' previously described operation.

Obviously the operation of thecylinder and casing maybe combined, byapplying power to both the gears 39 and 40, so as to rotate fthe casing4and cylinder simultaneously in the opposite-directions A and Brespectively.` This, however, would probably not benecessary,exceptfperhapsin unusual cases, as the same result would beaccomplished by increasing the rate of speed of either thecylinder'orcasing whilethe other was heldstationary. v

The operation of the device as a motor, it is thought will ybe readilyunderstood without detailed description, as it is merely the reverse of,the operation of thev pump. When so used, iluidunder pressure isintroduced through whatwas the discharge side ofv thepump, viz. throughthe pipe 16, hollow :shaft 13, cylinder chamber 24; and slot 27 and thisfluid `acts tojenlarge the compartments,ybetween the `partitions 30,which are incommunication lwith the slot 27, and to eifect suchenlargementcauses the cylinder 10orcasing 7--8.-9, lor both to rotate.By adjusting the set screws 42,7and 44,. r0- tation `of either thecylinder or casing orv both is permitted, and power .is furnishedfromthe device by connections made with the gears 39 and 4:0. ff A VTheoperation of the modified form of device Ashown in Figs. 10 and 11 issubstantiaily the same as that described for the structure of Figs. 1to` 9inclusive, except as `to the time and point of Contact of theVpartition L.l5 with the cylinder wall and with one another, Vwhich wasclearly pointed: outJ inl the description of4 this particular;structure, andv further description of itsoperation is. believed to be`unnecessary. f
